Specification of Letters Patent.

Patented oct. so, 1914.

Application filed December 14, 1907. Serial No. 406,482.

.To all whom it may concern Be it known that I, J OHN AsBURY SMITH,

.a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of. Pennsylvania, have invented a new 5 anduseful Register for Adding-Machines, of which the following is a specification.

This invention relates to a totalizer or chine, such for instance as the Elliott-Fisher billing machine of commerce, exemplified in Patents Nos. 820,879 and 829,971 r01 1 and others subordinate thereto, the preferred embod1mentof the invention' resides Laganke and.Smith.-

. -It may be stated by way of introduction, that the totalizer 'or register, shown in the patents identified, is adapted for uniform addition, that is to say, addition in which the-various denominations, in which the value is embraced, each have the same numericallimit of value, as for instance the decimal system, wherein the unit of value of each denomination is ten times the unit value of the denomination of next lower order. It has been proposed, however, to arrange totalizers, of the character under consideration, for nonuniform addition. that is to say, addition wherein the limits of value of the several denominations are different, for instance pints, quarts and gallons, wherein the limit of value of the pints denomination is two, of the quarts denomination four, and of each gallon denomination ten.

Several of the constructions proposed for facilitating non-uniform addition are shown in my co-pending application No. 404,020. In such proposed constructions, however, the desired result is attained by utilizing number wheels of different diameters, eccentrically mounted with respect to each other, upon separate eccentrically arranged shafts extending in opposite directions from a partition which subdivides the register casing into separate compartments. The stated characteristics of the registers devised for non-uniform addition constitute material variations from the standard Elliott-Fisher totalizer construction, in which, as shown in the patents identified, all of the number wheels are mounted on the same shaft and are of uniform diameter.

It is obviously desirable, in the economy of manufacture, to have all registers as near iiflcommon standard of construction aspossi- To this end the object'of the present invention is'to produce a totalizer adapted for the performance of non-uniform addition without necessitating the employment of number wheels of different diameters or eccentrically mounted. 1 I

Another object of the invention isto produce a totalizer adapted :for the.-- automatic addition of minutes and hours, as numbers representing minute and hour values are typewritten in a column. 5

To the accomplishmentfof these' objects inthose features'of construction and arrangement to be hereinafter described, illustrated in the accompanying drawings, and succinctly defined in the appended claims.

In said.drawingsfFigurezlris afrontelvation of the registeinf Fig.'2 .is" a' similar view :with a portion of the register casing removed to facilitate the disclosure. of hidden parts. Fig. 3 is a Vertical sectional view .of the same- Fig. .4 is amplan view of the major portion of the mechanism housed in. the register casing, the front wall of the latter being shown in section. Fig. 5 is a longitudinal sectional View on the line 5-5 of Fig. 3. Fig. 6 is a section on the line a:w of Fig. 3, looking in the direction indicated by the arrow. Fig. 7 is a longitudinal section on the line y-y of Fig. 3, looking in the direction indicated by the arrow. Fig. 8 is another longitudinal section on the line 22 of Fig. 3, looking to the right as indicated by the arrow, and Fig. 9 is a detail perspective view of the tens of minutes wheel.

Each part, wherever shown, is indicated by the same reference character.

As already stated, the totalizer, register or computing device to be described is intended for use as a part of a combined typewriting and adding machine the keys of which operate the printing mechanism to print numbers in a column, and also cause the simultaneous operation of a master means which is presented, by the movement of the typewriter carriage, in coiiperative relation with successive denominational members of the computing device. In certain aspects of the invention, however, it involves patentable novelty which relates 110 of an Elliott-Fisher typewriter-and is disposed for actuation by a master wheel mounted -ozi* the carriage of the. typewriter I and rotatable different distances upon the. depression of the numeral -keys.- Aregisten supporting bar '1' is shown/in Figsfi to 8 inclusive of the drawings. The register, supported upon this bar and shiftable along the same to different-column positions, -em f braces a casing 1, within which the'coinputing and registering mechanism is assembled.

In the present instance'this mechanism is designed to add minutes and hours'and'to register the total in view ofmhe operator of the typewriter so that the result :may be typewritten at the foot ofthe column with out:necessity for mental=calculation In the upper front corner of the casing ismounted a transverse shaft 2. This shaft is journaled in the opposite side walls'of the casing and is passed through 'a partition 3 which snbdivides the casing into'left and right hand compartments .4 and: 5.. -A similar shaft 6 is located below the shaft 2 and is likewise journaled in the sidewalls of the casing. These shafts support certain cooperatingelements locatedin .both the left and'right hand compartments 4 and 5. The mechanism located in the left :hand compartment is not novel, but will be first described, as a' .thorough understanding of what is old in the art will materially aid in the comprehension of the novel features which have been introduced in the register construction for the purpose of accomplishing non-uniform additioir- Proceeding then to describe the mechanism in the left hand compartment 4, a series of identical, uniformly-spaced denominational members or number wheels 0', (l, e, f, g and h are rotatably mounted on'tlie number wheel shaft 2, to the left of the partition 3, and are formed with ten peripheral teeth upon the outer faces of which are displayed the digits 0 to 9 inclusive. In the present instance these wheels represent units, tens, hundreds, thousands, ten-thousands, hundred-thousands and millions of hours and may be termed collectively the hours wheels.

On the shaft (3 at the left of the partition 3 are mounted a corresponding series of operating wheels or idlers c, (i, e, f, g and h, each of which meshes with one of the superadjacent number wheels and is adapted to be engaged and rotated by a master wheel M, for the purpose of transmitting motion from said master wheel to the respective number wheels 0', (1', etc. As is well understood in the art, the master wheel engages the several idlers in succession as the printing point of the typewriter moves from one denominational.position of the column to another. As adigit is printed in a given order of the column the master wheel is rotated a number of increments, or units of movement, corresponding to the value of the digit, thus causing the number wheel of corresponding denominational position to be rotated acorrespon'ding number of increments, for the purpose of accumulating upon said wheel. the value of'the'dig'it printed. Cooperating-with each of the Operating ,wheelsor-idlers c,'d, etc., is a spring-urged locator 7 which tends to accurately-position thesewheels sothat their teeth will be normally=located in alinement to facilitate the lateralpassage of the master Wheel across the series -of idlers.

The carrying mechanism 'forltlze hours wheels.I-t will of course be understood that a mechanism-of this character-necessarily embodies carrying mechanism, that is tosay, mechanism whereby, when 'anyugiven wheel has accumulated the'limit of value of that particular denomination, such value-will be carried: or: transferred to the adj acent wheel of'higher order. For this purpose a series of carrying levers 8 are fulcrumed on a'rod 9 extending transversely of thez casing adjacent to its lower rear corner, see .Fig. 5. Each of these levers 8 has a depending short arm '10 connected to one end of a spring 11 the opposite or rear end of which is secured to a fixed. part of the casing. The spring 11 tends constantly to draw the short arm 10 of the lever rearwardly and thus cause the long arm 12 of said lever to swing downwardly.

The forwardly disposed long arm 12 of each carrying lever 8 is bifurcated to form a locking end 13 and a guide lug 14. The end 13 is designed to engage between two teeth of the adjacent idler to lock the latter when the lever is swung down, and the lug 14 is guided in a kerfed guide-bar 15 to prevent lateral movement of the lever. From the locking end or arm 13 of the lever 8 is swung a carrying dog 16 designed to extend over a tooth of the operating wheel or idler served or operated by the lever. Thus when the lever is operated, its transfer dog, by reason of its engagement with a tooth of the adjacent idler, will advance said idler one increment or unit of movement and thus ef fect a similar advance of the number wheel engaged by said idler.

The operation of each transfer lever 8 is controlled by a selector 17 which is operated by the adjacent wheel of lower order. The selectors 17 are in the form of substan tially triangular swinging plates pivoted upon a transverse bar 18 and yieldingly retained in normal position by springs 19, as'

back, its inturned edge 20 will come opposite the notch in the lever and thus allow the lever to drop for the purpose heretofore stated. I

Each selector 17 is arranged to be operated by the adjacent idler to the right of the selector. The selectors 17 are mounted opposite the spaces between the idlers a, 1), etc., and each has a forwardly extended contact plate 22 located between two adjacent wheels and arranged to be operated by a carryingllug 23 extended laterally from the idlerto t e right of the selector. Each idler a, 2), etc., is.provided with a single transfer or carrying lug 23 and this lug is so located that when the number wheel engaged by the idler moves from 9 to 0, or in. other words, reaches the limit of its value, the lug will engage the contact plate 22 of a selector and thus swing the latter back. This backward movement of the selector will effect the release of the transfer leverv to the left thereof and said transfer lever will swing down under the impulse of its spring -11 and will, throughthe medium of its transfer dog 16, rotate the next adjacent idler to the left a single increment, thereby causing said idler to advance or carry the adjacent number wheel one unit of movement to accumulate thereon the value represented by one complete rotation of the wheel of next lower order. In other words, when the units wheel 0, for instance, has been-operated nine increments, and thus displays 5) at the sight opening, the next increment of movement of said wheel will display the 0 thereon at the sight opening and will cause the operation of a selector 1'? to release a transfer lever 8 and thus (allsc said transfer lever to advance the nzuuher wheel ofnext higher order, to-wit, the tens wheel (I, one increment, to present the 1 thereon at the sight openin and thus cause the registration of 10, which is the limit of value of the wheel a. The wheel 0 may hen be operated independently for nine additional increments, and upon the next increment will again cause the next higher wheel (l to be advanced, and so on ii'nlciiuitely, each wheel carrying to the next when its limit of value is reached.

The transfer dogs it necessarily have sufficient backward movement to prevent them from obstructing the further movement of an idler which has been advanced by the dog. It is usual therefore to provide vibrators 24 mounted on a transverse rod 25 and engaging the lower ends of the dogs 16 to urge the same into engagement with the wheels a, 1), etc., at the proper time. These vibrators are usually extended through the front ofthe easing 1, as shown, and their forwardly extended ends 26 are depressed by a part carried by the typewriting carriage, in a mannerin which those familiar with the art are acquainted.

. The means for restoring the carrying le'vers andmelectors to normal position. This mechanism constitutes no part of my present invention, except in so far as it may enter into novel combination with features to be described. In :order that the entire mechanism of theregister may be fully comprehended, however, it may be stated that a restoring rocker27 is swung from a bar 28 extended transversely of the casing and is geared to a slide 29 automatically operated upon the retraction;, of ,the typewriter carriage-t0 swing the rocker 27 .and cause the sametdelevate or reset thecarrying levers 8 and to swing the selectors17to their set positions. 2 v

The meam for resetting the hours wheels to 2er0 ...-After.a computation has been effected, it is necessary to clear theregister, that is to say, the numberwheels'must be reset to zero in order that-another computation may be effected, Toaccomplish this purpose, a resetting lei-c1130 is mounted at. the left hand side of the casing and is pro videdat its rear end with ahandle 31 by which it may be manipulated. At the front end of the lever is a segmental rack 32 which meshes with a gear wheel 33 fixed to the shaft 6,.see Figs. 3, 4 and 5. Also fixed to the shaft ('3, are a series of reseting cams 34 which alternate with the wheels 0, d, etc., and are formed with shoulders Upon the left hand face of each wheel a, l), etc., is mounted a resetting dog 36 urged against the periphery of an adjacent cam 34 by a spring 37. The shaft 6 and the cams 34 thereon are normally stationary. Therefore, as the primary or operating wheels 6, cl, etc., are rotated during the operation of the register, the resetting dogs 36 thereon merely travel idly around the cams 3i. These dogs in the normal or zero positions of the wheels are located just in advance of the shoulders 35 of the resettin cams, which shoulders are alined. There ore, when it is desired to reset the register, the handle 31 is grasped by the operator and the resetting lever 30 is swung in a manner to cause the rack 32 to rotate the gear 33 which, being fixed to the shaft 6, rotates the latter and the cams 3% thereon. This rotation of the cams will cause the shoulders 35 thereof to engage the dogs 36 on the adjacent wheels at, 7), etc., and as the shaft is given slightly more than a complete rotation, the wheels 0, d, etc, will be rotated to reset the registering wheels 0', d, etc. Having reset the register, the lever 30- is swung back to its normal position, the shaft 6 and the reset-.

the wheels will therefore bein locked condition. As the wheels must be unlocked before they can be reset, the lever 30 is provided with a cam 38 coacting with a slide retracting lever 39 operatively connected to the slide 29 and urged in one direction by a spring 40. The initial 'movement of the resetting lever 30 causes the cam 38 to operate the lever 39 to retract the slide 29, which in turn causes the rocker 27 to reset the transfer levers 8 and selectors'17,'the parts being so-timed thatthe' locking ends 13 of the transfer-levers8 will release the primary wheels a, 6, etc,- beforeany of the resetting dogs 36 are picked up by the cams- 34'.

It has already been explained that the movement of the wheels from 9 to 0 effects the operation of'the'selectors 17 and trans fer levers 8 to carry values from one de nomination to another. It follows that this action will alsdtakeplace just before the wheels reach their fully reset positions and consequently" when the wheels" have been reset they will be in locked condition, since the levers 8 will be depressed. Therefore, mechanism -is provided, whereby after the rocker 27' has been operated by the initial movement of the resetting lever 30 to reset the transfer levers 8 and the selectors 17, said rocker will move back slightly so as to allow the backward swinging of the selectors by the wheels during the resetting thereof, without, however, permitting the transfer levers to drop when released by the selectors. The mechanism to which reference has just been made is so arranged that upon the retraction of the wheel resetting lever 30, the rocker 27 will be permitted to again move forward to reset the selectors which have been swung back during the resetting operation, after which said mechanism, which is in effect a stop mechanism, will be operated by the resetting lever to permit the rocker and its associated parts to be wholly retracted to normal position. The stop mechanism, which cooperates with the rocker 27 and the resetting lever 30, is clearly shown in Fig. 6 of the drawings, and includes a vertically reeiproeatory stop 57 cooperating with a pin or stop 58 projecting from one side of the lever 39. The stop 57 is carried at the lower end of a slide 59, held against the left hand wall of the casing by a suitable retainer (30 and normally engaged and held depressed by the lever 30 against the-resistance of a spring (31.

This mechanism is fully described and claimed in my co-pending applicationNo'. 404,020 and constitutes no part of my present invention, except in so far as it may enter into novel combination with the distinguishing features of the register described herein. The various positions of the parts during the resetting operation have therefore not been illustrated, and the following brief description of the operation will therefore suilice.

When the resetting'lever-3O is thrown up it will operate the lever 39, which in turn. will operate the rocker 27 to reset such of the transfer levers and selectors as may have been left in operated condition at-the completion of the last computation. Incidental to this operation the pin 58 on the lever 39 will have moved back beyond the stop 57 and said stop will have been elevated by the spring 61 toa position in advance of the stop. As the elevation of the lever 30 is continued to reset the wheels," saidlever will move out of'co action with the lever 39'and thus permit the spring lO to' swing the lever 39 in a forward direction until thepin 58 is arrested by the stop 57. Thislimited movement of the lever 39 will cause it to slightly retract the rocker 27, such retraction being just suflicient to permit'the selectors to beswung backduring the resetting of the wheels withoutremovingthe' rocker from its supporting position beneath the transfer levers 8. As the {resetting lever completes its upward-excursion, the movement of the wheels from 9'to 0 will throw back the selectors, which obviously must be reset before the register can be again operated to effect a computation. "Therefore, as the resetting lever 30 is retracted toward its normal position, it will again coact with the h-vr-r 39 moving the pin 58 back from the stop 57 and thus causing the rocker 27 to be operated to reset the selectors 17. Continued retractile movement of the lever 30 will move it out of coactive relation with the lever 39 and will depress the stop 57 out of the path of the pin 58 and thus allow the spring 40 to restore the lever 39, the slide 29, and the rocker 27 to normal position.

The mechanism thus far described is that which is housed in the left hand compartment at of the casing and is adapted for what I term uniform addition, since the several denominations of hours, as for instance units, tens, hundreds, etc., of hours. have uniform limits of value, the value of each denomination being ten.

The mechanism in the right hand compartment of the casing, to-wz't, the minutes wheels and their cooperating parta-J shall now proceed to describe the mechanism housed within the left hand compartment 5 of the casing. This mechanism includes the units and tens of minutes wheels a and b,

I mounted loosely on the shaft 2, has ten peripheral teeth bearing the digits-O to 9 inclusive, and meshes directly with a primary wheel or idler a on the shaft 6. v

The tens of minutes wheel I) difi'ers materially both in construction and mounting from the other registering "wheels. This wheel, while of the same diameter as the other registering wheels, is not peripherally toothed, andinsteadof bearing a single series of ten digits, has displayed upon its periphery two series of digits each ranging from 0 to 5 inclusive. 1 This wheel is therefore what may be termed a twelve-incre ment wheel, as distinguishedfrom the other registering wheels, all of which have ten increments or units of movement during-each complete rotationth'ereof; The reason for this variation between the tens of minutes wheel and the other registering wheels is that the limit of value of the tens-of minutes denomination is six instead of ten, and as it is not desirable to '3 utilize a six-increment wheel, a twelve-increment wheel is utilized and is made to carry twice for each complete rotation thereof. Nevertheless, the Wheel b must be operated byits-primary' wheel or' idler b and said idler must correspond to the other idlers in order to accommodate the As each idler is a ten-' same master wheel. increment wheel, that is to say, advances ten units of movement for each rotation, and as the tens of minutes wheel I) is a twelveincrement wheel, and is nevertheless of the same diameter as its idler, it follows that a train of gearing must be utilized to communicate motion from the idler b to the wheel I) in order that when the idler is advanced one increment, corresponding to onetenth of its rotary movement, the tens of minutes wheel I) will be rotated a single increment, corresponding to one-twelfth of its complete movement. For this reason the idler I) is mounted upon the hub of a gear wheel 41 disposed closely adjacent to the right hand side of the partition 3, while the wheel I) is similarly fixed upon the hub of a gear wheel 42 similarly disposed adjacent to'the partition. The gears 41 and 42 are of different diameters and bear the relation of ten to twelve, the gear 11 preferably having fifteen teeth and the gear 42 eighteen teeth, as shown in Fig. 6. The geais 41 and 12 are geared together by means of an idle gear 43 mounted on a stud shaft 44 screwed into the partition 3, the size of this gear being immaterial.

It will now be seen that upon the rotation of the idler b any given number of increments, the tens of minutes wheel will be rotated a like number of increments, notwithstanding the fact that the units of movement of these wheels differ in extent.

. It will also be noted that by reason of the interposition of the idle gear 4A the wheel I) will be rotated in a direction opposite to the direction of rotation of the other registering wheels, all of the primary wheels or idlers ato h inclusive being rotated in a uniform ,direction when operated by the master lwhe'el; Attention is also directed to the fact that by reason of the interposition of the gear4'2 and the partition '3 between the wheels I)" and '0', these wheels are separated by adis tance-equal to a-letter space of the typewriter and that the'wheels a'and b are similarlyspaced 1 apart by a'spacing collar 45 and=a reset cam, which will be presently described. Furthermore, the fact that the wheels I) andQ-b' are not directly geared makes it necessary to offset the-*primary wheel or idler-b to one side of the wheel I) and this requisite, in connection with the spacegoccupiedby the gearing and the'partition, separates'the'wheels' b and a by an interval=equal to two letter spaces of the type- WritiiIig 'machine, In writing, however,

there will not be a space between units and tens 'of minutes, since the wheels a and b occupy adjacent letter spaee'positions, but

two spacesfivill bccur between tensof minutes and hours, so that the reading of the number will be properly facilitated.

- The means for carryi'rig from units to tens of -minutes' and from tens of minutes to hours.''The means'whereby the limit of avalue-is carried-from the units of minutes wheel a to the tens of ininutes wheel b is precisely like the carrying mechanism heretofore described, a transfer lever 8 being farranged opposite the idler b and being 1011 the idler a.

controlled by a selector 17 operated by a lug Therefore, in transferring ;from the wheel a to the wheel 7), there is absolutely no difference, either in the con struotion or operation of the mechanism,

ffrom a similar function to effect carrying from one hour .wheel to the next, except for ;the fact that the idler Z1, when operated by the transfer lever 8,--does not directly ad- Vance the wheel 12, but causes the advance @of the same through the intermediate gear ;ing 41, 42 and 43.

The operation of carrying from the tens of minutes wheel I) to the units of hours wheel 0 is different.

understood by reference more particularly to Fig. 6. The transfer lever 8 for the units of hours wheel 0 is precisely like the other transfer levers and operates in exactly the same manner when released to advance the idler a and its number wheel 0 one increment. The selector 1'? for this lever 18 somewhat different from the selectors described, in this, that it has a forwardly extended end i6 deflected laterally through an opening 4:? in the partition 3, see Figs. 1 and 6, and having its extremity 48 located in the path of two triangular carrying lugs 4:9 and 50 which project laterally from the left hand side face of the tens of minutes wheel I), see Figs. 2, 3, (i and 9. During the sixth increment of movement of the wheel 6 and also during the final or twelfth increment of movement thereof, or in other words, whenever said wheel moves from 5 to 0, the value accumulated thereon will be transferred to theunits of hours wheel 0,, since one of'the lugs 49 or 50-, as the case may be, will depress the forward extremity 48 of the selector l7} and will cause the same. to release thetra-nsfer lever of the wheel 0',

' The resetting of the minutes wheels.The resetting of the minutes wheels is effected simultaneously with the resetting of the hours wheels by the manipulation of the resetting lever 30. The mechanism whereby the manipulation of this lever effects the resetting of the units of minutes wheel a is identical with that heretofore described for resetting the hours wheel. That is to say, aresetting cam 34, mounted on the shaft 6, picks up a dog 36 on the idler av and thus r0- tates said idler to cause the same'to reset the units ofminutes wheel a in mesh therewith, The tens of minutes wheel 6, however,'cannot be reset in this manner from its idlenbecause one complete rotation of the idler would only effect ten-twelfths of a complete rotation of the wheel I). Therefore special provision is made, for resetting the wheel I).

On the right hand side face of the wheel b is mounted a resetting dog 51 similar to the dogs 36 and arranged to be picked up by a, resetting cam 52 fixed to the registering wheel shaft 2 between the wheel Z) and the spacer 45. The right hand ends of the two shafts 2 and 6 are geared together by gears 53, at and 5:3, see Fig. 8, so proportioncd that when the shaft 6 is rotated by the manipnlationof the resetting lever 30 the shaft will be rotated in like degree and in the same direction through the medium of the-gearing. It follows that when the resetting lever 30 isope-rated, the registering wheels a, c, d", e, f, g and it" will be reset by their idlers which are picked up by resetting cams on the shaft 6, while the tens of minutes wheel 1/ will be reset by the cam 52 on thenumber wheel shaft 2, this reset-- ting movement of the wheel I), like the operating movement thereof, being in a direction opposite to the direction of movement of the other number wheels. It may be incidentally remarked that the lower ends of the several selectors 17 are retained against lateral movement by the transfer levers 8 located at opposite sides thereof, see Fig. 4, and in order to prevent lateral movement of the selector for the transfer lever at the extreme right hand end of the .series, a guide-bar 56 is provided at the right hand side of the selector, as shown in Fig. 8. It will, of course, be understood that in the operation of resetting the register the rocker 27 coacts with the entire complement-cf transfer levers 8 and selectors l7 and 17, precisely in themanner heretofore described in connection with the mechanism located exclusively in the left hand compartment of the casing. M 1 1 '5':

Brief sumnwry+To briefly summarize, the described register ;-.is designed for :the addition f minutcsland; hours, the registering .wheelsirepresenting units of minutes, tens of minutes, ;and-sunits,wtens; hundreds, thousands, ten-thousands jandi hundredthow. sands of hours: Each 1 ofz these denominations has a limit of, value of ten except'the tens. of minutes wheel b, thelimitiofivalue of which denomination is six; Therefore, when ten units of minutes are accumulated upon the units of minutes wheel a' ;the value is transferred from said wheelto thetens of minutes wheel 6, a'nd-when'six tens ofiminutes have been accumillated onthe wheel 6', the value thereof,-which'is one hour, is transferred to the unitsofhonrswheelcubSimilarly, when'ten units have been accumulated on any hours wheel, the limitoftvalue. of the particular denomination represented by that wheel is transferred toxthe hour wheel of next higher order- It is to be understood, however, that the master wheel operates any one of-the several registering wheels through the primary wheels 0, b, etc, the value of the digit printed in any denomination being simultaneously accumulated upon'the registering wheel occupying a corresponding d'emom-irrational position.

It is thought-that from the foregoing, the construction and operation of this register will be fully comprehended, but while the present embodiment of the invention is thought at this time to be preferable, I wish to he understood as reserving the right to effect such changes, modifications, and variations of the illustrated structure as may come fairly within the scope of the protection prayed.
